Christianity is called the great confession, but most Christians who are defeated in life are defeated because they believe and affirm the wrong things. They have spoken the words of the enemy. And those words hold them in bondage. Proverbs 6:1-2 says, "...Thou art snared with the words of thy mouth."
Faith filled words will put you over. Fear filled words will defeat you.
Words are the most powerful thing in the universe.
Man is a spirit being, very capable of operating on the same level of faith as God. We read in Mark 9:23, "Jesus said unto him, If thou canst believe, all things are possible to him that believeth." Matthew 17:20 says, "And Jesus said unto them, Because of your unbelief. for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you." Mark 11:23 says, "For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith."
This is not theory. It is fact. It is spiritual law. It works every time it is applied correctly. This IS A SPIRITUAL LAW. God never does anything without saying it first. God is a faith God. God released His faith in Words. "And Jesus answering saith unto them, Have faith in God" (Mark 11:22). A more literal translation of the above verse says, "Have the God kind of faith, or faith of God."
Ephesians 5:1 literally tells us to be imitators of God as children imitate their parents.
To imitate God, you must talk like Him and act like Him.
He would not ask you to do something you are not capable of doing.
Jesus operated in the faith principles of Mark 11:23, and Matthew 17:20 while He was on earth.
He spoke to the wind and sea.
He spoke to demons.
He spoke to the fig tree.
He even spoke to dead men.
The wind, sea, tree, demons, and even the dead were obedient to what He said.
He operated in the God kind of faith. God is a faith God. God released His faith in Words.
Jesus was imitating His Father and getting the same results as His Father.
In John 14:12 Jesus said, "...He that believeth on me the works that I do shall he do also; and greater...." These principles of faith are based on spiritual laws.
They work for whosoever will apply these laws. You set them in motion by the words of your mouth. Do you really want all the negative things you have been confessing to come to pass? Are you believing for those things?
If Jesus came to you personally and said, from this day forward it will come to pass, that everything you say will happen exactly as you say it; would that change your vocabulary? I believe you would.
